Neglected firm effect

Neglected firm effect is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Neglected firm effect rather than just read about it. In short: The neglected firm effect is the market anomaly phenomenon of lesser-known firms producing abnormally high returns on their stocks. The companies that are followed by fewer analysts will earn higher returns on average than companies that are followed by many analysts.

Key takeaways

Neglected firm effect belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Neglected firm effect to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Neglected firm effect from memory before moving on to harder problems.

Reference excerpt

The neglected firm effect is the market anomaly phenomenon of lesser-known firms producing abnormally high returns on their stocks. The companies that are followed by fewer analysts will earn higher returns on average than companies that are followed by many analysts. The abnormally high return exhibited by neglected firms may be due to the lower liquidity or higher risks associated with the stock. At the same time, the impact on returns, and regarding earnings management is not always clear. According to Investopedia: "Neglected firms are usually the small firms that analysts tend to ignore. Information available on these companies tends to be limited to those items that are required by law, on the other hand, have a higher profile, which provides large amounts of high quality information (in addition to legally required forms) to institutional investors such as pension or mutual fund companies."

Worked examples

Example 1 — a first encounter with Neglected firm effect

Start with the simplest possible case. Write down what Neglected firm effect claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Neglected firm effect before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Neglected firm effect ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Neglected firm effect

In research: Neglected firm effect appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Neglected firm effect in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Neglected firm effect is common in secondary-school and first-year university syllabi. It links to neighbouring topics Behavioral finance, Efficient-market hypothesis, Finance stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Neglected firm effect outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
